FAQs
1. How do I know if my headlight switch is faulty?
A faulty headlight switch will either not turn on the headlights or only turn them on intermittently. You can test the switch using a multimeter to see if it’s delivering the correct voltage to the bulbs.
2. Can a bad relay cause both headlights to stop working?
Yes, a bad relay can cause both headlights to stop working. The relay is responsible for delivering power to the bulbs, and if it fails, the bulbs won’t turn on.
3. How do I replace a blown headlight fuse?
To replace a blown headlight fuse, locate the fuse box in your 2011 Chevy Malibu. Refer to your owner’s manual to identify which fuse controls the headlights. Use a fuse puller to remove the blown fuse and replace it with a new one of the same amperage rating.
4. Can I replace my headlight wiring harness myself?
Yes, you can replace your headlight wiring harness yourself. However, it’s essential to have some basic electrical knowledge and the right tools to avoid causing further damage to your wiring system. If you’re not confident, it’s best to seek professional help.
